World Record Breaking Lego Tower

What do you do when you have control over 3,000 bored kids? You make them build a 460,000 brick Lego Tower. Built in Rathaus Platz, Vienna, this structure took four days to build. The tower consists of 121 plates that was built by over 3000 kids using 2 x 4 Lego bricks. I hope they got free LEGO stuff for this. [GizModo]
